    Default Front fork grinding noise

    Trying to sort marydolls gsx600f front forks out.
    they make a noise like the spring is grinding against something .
    id changed the seals and renewed the oil cleaning everything weekly clean.
    ive now renewed the bushes top and bottom.
    even tried with a longer bandit spring without the spacers
    but it still makes the grinding noise
    i can't fit the bandit forks as they are different sizes of brake mountings .shame as they were quiet in operation.
    ive even thought about swapping the bandit damping rods etc over but they won't fit and I don't want to go drilling a larger hole in the gsf fork sliders to fit the thicker damping bolt .

    Noise both on and off the bike when compressed/released ?

    I wouldn't worry about it myself. Could even be too clean inside, perhaps the spring needs covering in oil to quiet it down?

    Is this the old model the teapot? I was always under the impression the bandit forks were the same is so.

    Take the forks out, take the springs out of the forks and see if it still makes the noise when you slide the forks up and down.

    Then it's the springs making the noise, are the little washer things on the tops of the springs (if it has them)

    not the original washers .ive just been out and I recon they are too big and the hole in the middle way too small .so I'll be getting the grinder out sometime over the weekend or check out my mates workshop for something better than the current washers..
    ill be getting new seals tomorrow
    cheers all

    How longs it been making this noise? Recently bought the bike? Since the beginning?

    I had a very slightly bent fork on my old 125 which was making a odd grinding noise, it was bent outwards so when I put the bolt on it pulled the fork inwards which caused a lot of pressure on rubbers.

    Easy way to tell if it's bent is the gap between the forks at the bottom. The front wheel with the spacers on should be an exact fit and slide in perfectly. If it's tight or there's space left over it's bent.

    Is it your knees and/or back making the noise? Have you got someone else to try compressing the forks....
